Patented Dec. 8, 1936 UNITED STATES PATENT OFFICE DUST MOP BUMPER AlfredD. Sund, Santa Rosa, Calif.

4 Claims.

This invention relates to dust mop bumpers, and has special reference toa resilient member adapted to be applied to the handle of a broom, dustmop, or similar cleaning implement, which will prevent marring of windowledges or other objects, against which the handle is struck to dislodgedirt from the broom or mop, and which will assist the rebound of thehandle during each stroke to magnify the shock imparted to the broom ormop.

The subject matter described in this specification, and illustrated inthe accompanying drawing, was originally part of my Patent No. 2,021,-335, allowed November 19, 1935, this being a division of the aforesaidpatent.

It is an object of the invention to provide a bumper for the handles ofbrooms or mops which has adjustable clamping means thereon enabling thebumper to be fitted to handles of difierent diameters.

Another object or" the invention is to provide a resilient bumper onwhich metal parts used for clamping the bumper to the implement handleare protected by portions of the bumper from coming in contact with andmarring, objects against which the handle is struck during the operationof shaking dust and dirt from the implement.

Another object of the invention is the provision of a humper which doesnot require that the broom or mop be held in any particular positionduring the operation of shaking the dust and dirt therefrom.

The invention possesses other objects and valuable features, some ofwhich, together with the foregoing will be set forth in thespecification hereunto annexed. It is to be understood however that theinvention is not to be limited to that species shown and described asvarious other embodiments may be employed within the scope of theappended claims.

Referring to the drawing:

Figure 1 is a side elevational view showing the bumper applied to thehandle of a dust mop and the position the latter occupies, in relationto a window, which is shown in light lines, during the operation ofcleaning the mop.

Figure 2 is a front elevation, partly in section, of the bumper. Theplane of section is indicated by the line 2-2 of Figure 3.

Figure 3 is a vertical sectional View of the bumper. The plane ofsection is indicated by the line 3--3 of Figure 2.

The invention comprises a rubber bumper, generally indicated by thenumeral 4, Figure l, which may be fitted to the handle 5 of a dust mopor broom 6. As is well known, the method employed in cleaning such mopsis to pass the handle 5 thereof through an open window I and by strikingthe handle 5 in successive strokes, against the ledge 8, cause the dirtand dust contained in the mop to be dislodged therefrom. The rubberbumper t, besides providing for protection of the ledge against beingmarred by the handle 5, during the cleaning operation, provides foradded rebound of the mop during each stroke and this added reboundcauses deep-seated dirt to be more rapidly released from the mop.

In detail, the bumper, as is shown in Figures 2 and 3, comprises acylindrical block of rubber provided wtih a central aperture 9 forreceiving the mop handle and a peripheral groove II] which provides apair of end flanges I I. In the groove III is positioned an arcuatestrap I2 having upturned ears I3 formed at its ends provided withapertures I4 for receiving a clamp screw I5. This clamp screw, inconjunction with the strap I2, is for diametrically compressing theaperture 9, after the bumper has been positioned on the handle 5, so asto cause the bumper to be securely affixed thereto.

During the operation of striking the bumper against the window ledge, orother solid object, one of the flanges I I will flex to a position whereit is interposed between the strap I2 and the ledge thereby protectingthe latter against being marred by the strap. At the end of the downwardstroke it will be evident that the rubber of the bumper will becompressed materially and this force stored in the bumper, together withthat stored in the flexed flange II, will rapidly overcome the momentumof the mop and accelerate the upstroke thereoi thereby imparting adecided shock to the mop and causing dislodgement of dirt therein whichwould not ordinarily be shaken out.

In addition to the features set forth above it will be seen that a mopequipped with the bumper of my invention may be cleaned without creatingbothersome noise to neighbors or day sleepers who may be in theimmediate vicinity; will be protected against handle breakage; and willbe capable of being more thoroughly cleaned in a shorter time than can amop not equipped with the bumper.

I claim:

1. A dust mop bumper comprising a resilient member having an aperturetherein for receiving the handle of a mop, said member having aperipheral groove therein, and means for compressing said resilientmember about said handle, said compressing means being disposed whollywithin said peripheral groove.

2. A dust mop bumper comprising a cylindrical resilient member having anaperture therein for receiving the handle of a mop, and means forcompressing said resilient member about said handle, said compressingmeans being disposed below the outermost surface of said member betweenthe periphery thereof and said aperture.

3. A dust mop bumper comprising a cylindrical resilient member having anaperture therein for receiving the handle of a mop, means forcompressing said resilient member about said handle, said compressingmeans being disposed about a portion of the periphery of said member andsaid aperture, and a pair of flexible flanges extending from said memberand projecting radially thereof to points beyond the radial extent ofsaid com pressing means.

4. A dust mop bumper comprising a cylindrical resilient member having anaperture therein for receiving the handle of a mop and means forcompressing said resilient member about said handle, said compressingmeans comprising an arcuate metallic strap about said member, a screwjoining the ends of said strap for drawing said ends together, and apairof flexible flanges extending from said member and enclosing said strapand said screw, said flanges being normally disposed in parallelrelationship transversely with respect to the axis of said aperture, andportions of each flange being flexible from said normal position to aposition parallel with said axis and overlying said strap when saidbumper is struck against an object.
